Annoyance is an emotion, too, even if Dave doesn't get much from it. He'll keep that bit that he's getting in reserve - it's definitely not enough that he can afford to go wasting energy willy-nilly.

Dave is expecting Bro to parry (it's Bro, after all), but it's still been so long since he's battled another flashstepper that that brief moment of consideration in his mind as he wonders what parts of the song is causing Bro's annoyance (though, frankly, as the lyrics spill forth from his phone, he finds himself inwardly cringing) dulls his senses enough that he isn't able to avoid the kick to his stomach.

Digging his heels into the dirt to keep from skidding back too far, Dave glances down... "Shit!" ...for just briefly enough to get a good gander at the giant footprint now marring his coat. This coat was expensive, goddamn it.
